Two or more of The tool of th present invention is a collapst e p s re preferab y used to insure lateral ible one, which when in operative positionis I stability; For thisreason, the pins are placed as adapted to have one end supported upon the a apart as D SS bIe i e head, d are s o side wall, or framing, of a room, and be rotatable pr j cting forwardly from' positions near the about the supported end to lift a board or sheet ends ofthe vertical flange l3.

The tical flange l3 ofthe tool project beyond the ends hinge ispreferably located at the bottom of the of the horizontal flange l and the proje i ends are offset rearwardly. This will permit a claw hammer, or other tool, to be inserted to pry loose the impaling pins l8. In using the tool, the body sections are opened by swinging about the hinge 3, and the rod 1 is 5 inserted through the openings 5 in the straps l and the openings 6 in the body section I. Rod 1]) is pushed through the openings far enough to project substantially the same distance on each side of the body. The handle 8 is swung down? 10 wardly from the recess l0 about-"its hinge 9 and, with wing nut I! adjusted so that head [2 may be moved about the pivot bolt l6 but will not swing freely thereon, the tool is lifted until, the head is substantially flush with the ceiling line. The tool is then thrust forward to sink. the impaling pins l8 into the side wall .of they room. In most cases, the pins will penetrate the horizontal stringers which form part of theroom framing and lie adj acent the ceiling. The tool will then be firmly anchored at its free end and will support the ceilingboard. The adjustability of. the head permits attachment to supports at' various angles, and makes it possible to anchor to members which otherwise would be inacces-' sible The board is placed upon the body of the. tool [while the tool is in an inclined position, the end of the board being pressed firmly against the, side wall framing; The outer end of the tool is" then lifted toposition the board" against th= ceiling joists. Th'e'handle permits the workman to achieve this while standing on the floor. The.. board may then be held while being secured in place. During the liftingv and holding'operation',

the body of the tool supports the board longitu dinally, whilerod land head I! furnish transversesupport. When the tool-is not in use it may be folded about the hinges .3 and 9 into compact form for storing'or transporting to another job.

While in 'the above, one practical embodiment 40 of the invention hasbeen disclosed in detail, it, will be understood that many changes may be made from the precise structure shown and describedwithin the scope of the invention as defined'by the appended claims.

,whatislclaimed is; A f V l .1; In'a lifting tool, a pair of hingedly connected 4 body sections. a supporting head pivotally connected to the free end of one of said body sections, a handle hingedly connected to the free end of the other said body section, and means to lock said body sections in longitudinal alignment. a part of said locking means comprising a rod projecting beyond opposite sides of said body sections to form a transverse support for material to be lifted .upon the tool.

211m a" lifting tool as 'claimedin'ielaim' 1. said head eiitendin'g transvrs'ely td the'fdiiec'tion of said body and having impaling pinsprojecting therefrom, whereby said head will cooperate with said rod in transversely supporting material to be lifte'dupon said tool.

, 3. In alifting tool as claimed in claim 1, a

recess in the body section carrying said handle "to receive said handle when folded.

4, In a lifting tool as claimed in claim 1, said head being positioned transversely to the direction of said body and having impaling pins projecting from spaced points thereon, and means for binding said head to said body to prevent free pivotal movement of said head with respect to said body. n

5. In a lifting tool as claimed in claim 1, said head being positioned transversely tothe direction of said'body and having impaling pins projecting from spaced points thereon, said pins having their butt ends joined to the head on a common plane and a portion of said head being raised out of the plane of joinder of .the butt ends of the pins with said head to provide an engaging surface for removing the'pins from a support; v
